Cyclones are large areas of swirling air with clouds and precipitation being formed inside.
Sometimes one can come across with spectacular atmospheric phenomena. Find out their scientific background, too!
Lateral compressive forces cause rocks to form folds. This is how fold mountains are formed.
Due to the external and internal forces of our planet, rocks undergo a constant cycle. Let’s learn the specifics of this process.
We can come across the remains of the Variscan and Caledonian mountain systems almost anywhere in the world.
The surface of the Earth has been formed into its present state both by external and internal forces. External forces shape the surface from the outside; hence, the name.
Upon the meeting of cold and warm air weather fronts develop that in most cases bring precipitation, too.
